Paper Abstract

An approach of ellipsometric measurements both from ambient media and from transparent or weakly absorbing substrate has been proposed to determine optical constants and thickness of anisotropic films. According to this approach the main refractive indices are calculated by an iterative procedure while an optimization is used to average the values obtained over the parameters measured at one or several incidence angles. The approach proposed has been used for a determination of optical constants and thickness of multimolecular Langmuir-Blodgett films based on the derivative of 5-[4-(stearoylamino)phenyl] isophthtalic acid.
